Just noticed now that the new build of Windows Azure Directory Synchronization Tool, is missing the DirSyncConfigShell.psc1 file.
Moreover, the Coexistence-Configuration PSSnapin is also gone. Trying to add the pssnapin would generate the error – The Windows PowerShell snap-in Coexistence-Configuration is not installed on this machine.

So if you’ve trying to use the known way to force a synchronization with DirSync, use these PowerShell commands to achieve what you were used to.
Import-Module DirSync
Start-OnlineCoexistenceSync

I can’t import the dirsync module. Our original dirsync got messed up when I upgraded from 2012 to 2012r2. I removed it and installed a newer version. No dirsync module. No coexistence-configuration option. Nothing to make it automatic again.
